AIMS There is a need for a brief, validated measure of quality of life (QOL) for children to monitor their adjustment to burn injuries. We aimed to apply a Rasch analysis to an existing measure of QOL from the dermatology literature to a clinical sample of pediatric burn patients. METHODS The Children's Dermatology Life Quality Index (CDLQI) was administered to pediatric burn patients (N = 253) during a standard clinic visit. Rasch analysis was used to examine psychometric properties of this measure with a burn sample. RESULTS The CDLQI showed an adequate fit to the Rasch model. Test difficulty is .61 logits greater than person ability. Results of item reliability and separation analyses were sufficiently strong and indicated a unidimensional latent trait. Person reliability (.74) and separation analyses (1.64) were moderate. Finally, the CDLQI was able to moderately separate the group of respondents into low and high levels of QOL impairments related to burn injuries. CONCLUSION The Rasch model demonstrated that the CDLQI is a reliable and valid scale that adequately measures QOL impairments in children following burn injuries.

评估小儿烧伤后儿童的生活质量损害：儿童皮肤病生活质量指数的Rasch分析。

目的有必要对儿童的生活质量（QOL）进行简短的验证，以监测其对烧伤的适应性。我们旨在将Rasch分析应用于从皮肤病学文献到儿科烧伤患者临床样本的现有QOL量度。方法在标准门诊就诊期间，对小儿烧伤患者（N = 253）进行儿童皮肤病生活质量指数（CDLQI）评估。Rasch分析用于检查烧伤样本的心理测量特性。结果CDLQI显示出与Rasch模型的适当拟合。测试难度比个人能力高0.61 logits。项目可靠性和分离度分析的结果足够强，表明具有一维潜伏性状。人员可靠性（.74）和分离分析（1.64）是中等的。最后，CDLQI能够将受访者群体分为与烧伤相关的QOL损伤的高低水平。结论Rasch模型证明CDLQI是一种可靠且有效的量表，可以充分测量烧伤后儿童的QOL损伤。
